I need the answer as soon as possible
4-A long shunt compound DC generator delivers a load current of 150A at 230V and has armature, series field and shunt field resistances of 0.0322, 0.0152 and 922 respectively. Calculate (i) induced emf (ii) total power generated and (iii) distribution of this power. 5-A four pole lap-connected armature of a DC shunt generator is required to supply the loads connected in parallel: (a) 5kW Geyser at 250 V and (b) 2.5kW lighting load also at 250V. The generator has an armature resistance 0.22 and a field resistance of 2502. The armature has 120 conductors in the slots and runs at 1000 rpm. Allowing 1V per brush for contact drops, find (1) Flux per pole, (2) armature current per parallel path
